When I was a kid, if you needed to get your teeth straightened, you had to get braces mounted on your teeth.
Rubber hands and a headgear assembly controlled the tension, and every month you’d go in for tightening and adjustment.
Now, you can get your teeth scanned, and they’ll 3-D print a series of clear plastic guides that align them.
No more painful mounting and twisting of the braces.
No more disgusting rubber bands.
No more ugly headgear.
And no more picking up spy signals from outer space.
My orthodontist smiles, says “Da! Is good?” and offers me vodka.
